Despite pushing Chief Operating Officer Sheryl Sandberg as the face of the company in recent months, Facebook does not have one woman on its board, according to the report.

That's in stark contract to most Fortune 500 companies. Of all those listed, only 11.3 percent of those companies did not have a woman on the board.

"It doesn’t make sense for a company that claims to be so forward looking to not have any women directors," Anne Mulcahy, a former chairman and chief executive officer of Xerox Corp., told Bloomberg. "If they just have an old boy’s network in the boardroom, they won’t have access to diverse ideas and strategies."

Companies, such as Google, Apple and LinkedIn all have at least one woman on the board.
